0-argument `view` errors

[penelopeysm]

I would have expected view(xx) to return a 0-dimensional DimArray here (tested on v0.30.1):

julia> x = [0.5]
1-element Vector{Float64}:
 0.5

julia> view(x)
0-dimensional view(::Array{Float64, 0}) with eltype Float64:
0.5

julia> xx = DimArray([0.5], (X,))
┌ 1-element DimArray{Float64, 1} ┐
├────────────────────────── dims ┤
  ↓ X
└────────────────────────────────┘
 0.5

julia> view(xx)
ERROR: ArgumentError: axes of the array (0) do not match number of dimensions (1)

This is a regression in 0.30. This worked in 0.29.27
